Freshen up your closets

Coffee is a natural deodorizing agent. Grind up coffee beans very fine, and place a few scoops into a cheesecloth sachet or reusable brew bag. We hang these easy-to-make sachets in a closet to clear up musty smells — just dangle from a hanger for a day or two. Other places worthy of these deodorizing pouches include stinky shoes, the refrigerator and the car.

Fertilize plants

Enrich the soil of flower beds by working coffee grounds directly into the dirt. This practice works especially well for beds containing roses, azaleas, rhododendrons, evergreen, camellias and other acid-loving plants.

Expert tip: Coffee grounds can actually create hyper-blue hydrangeas. The grounds increase the acidity of the soil, which helps them absorb aluminum and creates the vibrant blooms.

Coffee grounds can help punch up the color in blue hydrangeas.

Repel insects

To create a protective border around plants and shrubs, form small rings of coffee grounds around the base. This will prevent unwanted critters like ants, slugs or snails from getting too close. Furthermore, sprinkle old grounds wherever you don't want bugs to appear.
